createVerticalBarChart

[Mike Isaacs]

I'm using the createVerticalBarChart() method of the ChartFactory (version 0.7.2 of JFreeChart).

It used to work fine, and I have not changed anything in the code. But now I have started getting a java.lang.NoClassDefFoundError on the call. This did not happen previously

I am in the process of upgrading to version 0.8.1, but also want to work out why the old graph has stopped working?

Any ideas?

Hi Mike,

Post the full text of the exception, and the versions of the jfreechart and jcommon jar files that you are using.

Regards,

DG.

Uprgraded to latest Version 0.8.1 of JFreeChart and JCommon. Getting a different error message, from the same line of code ( JFreeChart chart = ChartFactory.createVerticalBarChart(title, categoryAxisLabel, valueAxisLabel,data,legend); )

java.lang.InternalError: Can't connect to X11 window server using ':1' as the value of the DISPLAY variable.

I've got a feeling something has changed in the environment of the OS that has stopped the charts from working.
